[0002]

2. Description of the Related Art A table is used for serving plates, containers, and tableware. When eating drinks, fruits, or prepared foods that are kept cold in the refrigerator at the time of eating, those foods should be removed from the refrigerator. I took them out, arranged them on the table, and ate them. In addition, when the food is kept cold again after the meal, it is transferred from the table to the refrigerator.

As described above, the work of moving foods back and forth between the dining table and the refrigerator is troublesome and inconvenient, and it takes a lot of time and effort to prepare and clean up the meals, and a large amount of time is wasted. Therefore, in order to eliminate such inconvenience, there has been proposed a structure in which a top plate is placed on the top of a refrigerator and food or the like can be arranged on the top plate so that it can be used as a dining table.

[0004]

Since the table of the prior art described above has the table and the refrigerator integrated with each other, the serving work can be performed relatively easily, but it is necessary to manually transfer the food between the table and the refrigerator. There was no change in what I did, so I could not reduce the work. In addition, when such an operation of storing and taking out food is attempted mechanically and automatically, there is a drawback that the structure is complicated and large in size, so that it cannot be put into practical use.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to automatically store and take out food from a table to a refrigerator without manual labor. Another object of the present invention is to provide a dining table with a refrigerator having a small and simple structure.
